Toriello-Carey syndrome

Toriello-Carey syndrome (TCS) is an extremely rare congenital disorder characterized by a combination of craniofacial anomalies, central nervous system malformations, and other systemic abnormalities. The condition was first described by Toriello and Carey in 1988. Key features include agenesis or hypoplasia of the corpus callosum, Robin sequence (micrognathia, glossoptosis, and cleft palate), telecanthus or hypertelorism, short palpebral fissures, small nose with anteverted nares, and laryngeal and airway anomalies. Affected individuals frequently present with significant developmental delay and intellectual disability. The syndrome affects multiple body systems. Neurological involvement includes structural brain malformations such as partial or complete agenesis of the corpus callosum, which contributes to developmental delays and hypotonia. Craniofacial features are prominent and may include Pierre Robin sequence, which can cause significant feeding and breathing difficulties in the neonatal period. Cardiac defects have been reported in some patients, adding to the complexity of medical management. Laryngeal abnormalities, including subglottic stenosis and laryngeal webs, can cause airway compromise requiring urgent intervention. There is no specific cure or targeted therapy for Toriello-Carey syndrome. Management is supportive and multidisciplinary, focusing on addressing individual symptoms. This may include surgical intervention for cleft palate or airway obstruction, cardiac surgery if congenital heart defects are present, and early developmental intervention programs. Feeding support, speech therapy, and physical therapy are important components of care. The prognosis varies depending on the severity of brain malformations and associated anomalies, with some patients experiencing significant morbidity in infancy due to airway and feeding complications.
